20140062782 | Method and System for Calibrating Group Delay Errors in a Combined GPS and GLONASS Receiver - A combined GPS and GLONASS receiver receives GPS signals and GLONASS signals. A calibration signal is generated utilizing the received GPS signals and/or the received GLONASS signals to offset group delay errors in the received GLONASS signals. The generated calibration signal is filtered through Kalman filters to estimate group delay variations in the received GLONASS signals. The estimated group error delay variations are combined with the received GLONASS signals to calibrate the received GLONASS signals by offsetting the estimated group error delay variations. When GPS signals are not available for use, the combined GPS and GLONASS receiver obtains group delay errors stored or in the received GLONASS signals to estimate calibration coefficients. The estimate calibration coefficients are updated utilizing received GPS and/or GLONASS signals. The updated estimated calibration coefficients are stored before turning off the combined GPS and GLONASS receiver to expedite calibrating of GLONASS signals received upon turning on. | 03-06-2014 |
20140077990 | Method and System for Utilizing Reduced Functionality Processing Channels in a GNSS Receiver - A global navigation satellite system (GNSS) receiver comprising one or more regular channel circuits and one or more sniff channel circuits may be operable, utilizing the sniff channel circuits, to monitor power levels of currently visible GNSS satellites which are not being utilized by the regular channel circuits. An alternative GNSS satellite from the currently monitored GNSS satellites may be selected by the GNSS receiver based on the monitored power levels. GNSS signals received from the selected alternative GNSS satellite may be processed by a regular channel circuit. The GNSS receiver may be operable to detect, for example, signal-to-noise ratios (SNRs) or carrier-to-noise density ratios (C/N0s) of the currently visible GNSS satellites utilizing the sniff channel circuits. The sniff channel circuits may not be utilized to generate GNSS measurements so that functionality of each of the sniff channel circuits may be reduced. | 03-20-2014 |
